To all whom it may concern: the pipes 9 against the plate 1). Between the Be it known that I, EUGEN ALBERT, a subgroups of pipes 11 g and the late I) there is arject of the King of Bavaria, residing at ranged a protecting-frame or the purpose of Schwabingerlandstrasse, Munich, in the reventing water sprayed against the late b. 60 Kingdom of Bavaria, Germany, have inventom. enetratin into the gas-pi es (1 t on h ed certain new and useful Improvements in their oles 7c. his protective ame can he Aplparatus for Backing Electros, of which the constituted by a flat iron frame m, guided in f owin is a specification, reference being the guides n 'n-of the frame 0 and provided hadto t e accompanying drawings, forming with a handle 0. To this flat iron frame m is 6 a part hereof. riveted a series of narrow curved metal strips The backs of electros used in tinting are 1). When the plate I) is heated, the frame m generally cast by first placing t em on the 1s in'the position shown in Fig. 2, in which bottom of a metal box, which is dipped into the metal strips are situated over the wathe molten metal to be applied to the electer-pipes 9. ,Be ore coolin the plate I) the tros in order that the electros may be brou ht frame m is shifted toward t e left, as in Fig. to the same temperature as the metal, after 2, so that the strips 1) come to lie over the which the electros are filled with the molten gas-pipes d, water thus being prevented from metal. The electros with the backs thus penetrating into the gas-pipes d. cast on are cooled by exposing them to a cold It will be obvious that protective means 7 5 current of air in a suitable device. In ad other than the frame m may be employed, if
